excel2access

Microsoft Excel類模塊，可讓您連接和操縱Microsoft Access數據庫。

您可以在沒有任何MS SQL知識的情況下與MS Access數據庫進行交互。數據庫類別在其中生成SQL並為您執行。

從數據庫中選擇數據的示例：

 ' Let's say you have a MS Access database which has a table called "TestTable":

' ID  text_field  binary_field  number_field
' 1   text-1      Yes           10
' 2   text-2      No            20
' 3   text-3      Yes           30
' 4   text-4      No            40
' 5   text-5      Yes           50


Dim db As New DatabaseUtility
Dim criteriaFields As New Collection, criteriaValues As New Collection, _
        selectionFields As New Collection
Dim results As New ADODB.Recordset
Dim dbName as String, dbPath as String

dbName = "NameOfTheMsAccessDatabase.accdb"
dbPath = "/Path/to/MS/Access/Database/"

' Establish connection with database
Call db.ConnectToDB(dbName, dbPath)

' Enter the fields you want to select in a collection
selectionFields.Add "text_field"
selectionFields.Add "binary_field"
selectionFields.Add "number_field"

' Enter criterias for your query in a collection
criteriaFields.Add "binary_field"
operators.Add "="
criteriaValues.Add "No"
    
criteriaFields.Add "number_field"
operators.Add ">"
criteriaValues.Add "20"

' Get the results in a ADODB.Recordset object
Set results = db.SelectRecords("TestTable", selectionFields, operators, criteriaFields, criteriaValues)

Call db.disconnectFromDB
Set db = Nothing

' results will have
' ID  text_field  binary_field  number_field
' 3   text-3      Yes           30
' 5   text-5      Yes           50

您也可以執行自己的查詢

 ExecuteSql(theSql As String) as ADODB.Recordset

在集合中的數據庫文件中獲取所有表的名稱：

 GetTableNames() As Collection

插入記錄：

 InsertRecord(theTable As String, theSetFields As Collection, theSetValues As Collection)

插入一個記錄：

 InsertRecord(theTable As String, theSetFields As Collection, theSetValues As Collection)

選擇多個記錄：

 SelectRecords(theTable As String, _
    Optional theSelectionFields As Collection, _
    Optional theCriteriaFields As Collection, Optional theCriteriaValues As Collection, _
    Optional theOperators As Collection, _
    Optional theDistinct As Boolean = False, _
    Optional theLimitBy As Double = 0, _
    Optional theOrderBy As String = "", Optional theAsc As Boolean = False) As ADODB.Recordset

在一個字段中獲取多個（或所有）值：

 SelectField(theTable As String, _
    theSelectionField As String, _
    Optional theCriteriaFields As Collection, Optional theCriteriaValues As Collection, _
    Optional theOperators As Collection, _
    Optional theDistinct As Boolean = False, _
    Optional theLimitBy As Double = 0, _
    Optional theOrderBy As String = "", Optional theAsc As Boolean = False, _
    Optional isBlankIncluded As Boolean = True) As Collection

更新記錄：

 UpdateRecords(theTable As String, _
    theSetFields As Collection, _
    theSetValues As Collection, _
    theCriteriaFields As Collection, _
    theCriteriaValues As Collection, _
    Optional theOperators As Collection)

在字段中選擇一個單元格

 SelectFieldCell(theTable As String, _
    theSelectionField As String, _
    theCriteriaFields As Collection, _
    theCriteriaValues As Collection, _
    Optional theOperators As Collection, _
    Optional theOrderBy As String = "", _
    Optional theAscending As Boolean) As Variant

根據標準獲得數字字段的單元格的總和

 SelectFieldSum(theTable As String, _
    theSelectionField As String, _
    theCriteriaFields As Collection, _
    theCriteriaValues As Collection, _
    Optional theOperators As Collection, _
    Optional theLimitBy As Double = 0, _
    Optional theOrderByFieldName As String = "", _
    Optional theAscending As Boolean) As Double

根據標準獲取數字字段的單元格

 SelectFieldCount(theTable As String, _
    theSelectionField As String, _
    theCriteriaFields As Collection, _
    theCriteriaValues As Collection, _
    Optional theOperators As Collection, _
    Optional theLimitBy As Double = 0, _
    Optional theOrderByFieldName As String = "", _
    Optional theAscending As Boolean) As Double

刪除記錄

 DeleteRecords(theTable As String, _
    theCriteriaFields As Collection, _
    theCriteriaValues As Collection, _
    Optional theOperators As Collection)
